Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_153026.3(PRICKLE1):c.1601G>A(p.Arg534Gln) variant causes a missense change. The variant allele was found at a frequency of 0.000126 in 1,614,048 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R534W) has been classified as Uncertain significance.

The p.R534Q variant (also known as c.1601G>A), located in coding exon 6 of the PRICKLE1 gene, results from a G to A substitution at nucleotide position 1601. The arginine at codon 534 is replaced by glutamine, an amino acid with highly similar properties. This nucleotide position is highly conserved in available vertebrate species. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Epilepsy, progressive myoclonic, 1B Uncertain:2
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 534 of the PRICKLE1 protein (p.Arg534Gln). This variant is present in population databases (rs756192425, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with PRICKLE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 281207). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt PRICKLE1 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
